Molecular Biology of Archaea Role of vapBC toxin-antitoxin loci in the thermal stress response of Sulfolobus solfataricus

open access: yes, 2020
TA (toxin-antitoxin) loci are ubiquitous in prokaryotic micro-organisms, including archaea, yet their physiological function is largely unknown. For example, preliminary reports have suggested that TA loci are microbial stress-response elements, although

Bioinformatics analysis of loci vapBC of the cyanobacteria Microcystis aeruginosa PCC 7806 and experimental characterization of putative toxins VapC29, VapC33 and VapC45

open access: yes, 2022
Sistemi toksin-antitoksin (TA) so sestavljeni iz dveh komponent. Toksin je praviloma stabilen protein, ki v celicah, kjer se izraža, deluje citostatično ali citotoksično, antitoksin pa je nestabilen protein ali RNA, ki preprečuje delovanje toksina in ...

Analysis of the role of VapBC-type toxin-antitoxin modules in growth, stress tolerance and drug tolerance in mycobacteria

open access: yes, 2011
Forty seven of the toxin-antitoxin modules in the genome of Mycobacterium tuberculosis belong to the VapBC family in which the VapC toxin is a member of the PIN-domain protein family associated with nuclease activity.

The effect of VapC29 overexpression on the growth and viability of M. smegmatis mc2155 and ΔvapBC strains.

open access: yes, 2018
The effect of conditionally expressing VapC29, VapBC29 or empty vector (EV) on growth (a) and cell viability (b) was examined in a wild-type and vapBC knockout strain of M. smegmatis mc2155.

Les systèmes Toxine-Antitoxine VapBC : des régulateurs de la symbiose fixatrice d'azote Rhizobium-Légumineuse

open access: yes, 2020
During the nitrogen-fixing symbiosis between the model legume Medicago truncatula and the rhizobiaceae Sinorhizobium meliloti, bacteria, differentiated into bacteroids within the nodule, reduce atmospheric nitrogen (N2) into ammonia (NH3), directly ...

Five Mtb VapC proteins display the same sequence specificity against 924 Pentaprobe RNA.

open access: yes, 2018
The ribonuclease activity of VapC1, 19, 27, 29 & 39 (2.9 μM) was tested against the 924 pentaprobe RNA (18 μM). Negative controls included no VapC (RNA only) at the beginning (RNA only 0) and end (RNA only 60) of the assay reaction, addition of EDTA, and
